Description

Technical Field

[0001] This invention relates to the field of current transformer manufacturing equipment technology, and more specifically, to a current transformer center copper sheet pressing machine. Background Technology

[0002] Current transformers are key components within electricity meters, primarily used to measure the actual current flowing through them. Together with the voltage acquisition devices within the meter, they complete the data collection and calculation of electrical energy. For certain models of current transformers, such as the patented product with application number CN202320597957.3, a central copper sheet needs to be installed inside the hollow cylinder at the center of the transformer, and then epoxy resin is used to fill and pot the space between the central copper sheet and the coil inside the transformer.

[0003] Pressing the center copper sheet into the current transformer is a crucial step in the manufacturing process. First, align the center copper sheet to be pressed with the mounting slot of the current transformer and place it in place. Then, place the current transformers to be pressed into the corresponding mounting holes on the tooling plate. Finally, apply pressure to the center copper sheet by pressing it vertically downward with the pressing plate, pressing the center copper sheet into place in one go.

[0004] Currently, during the pressing operation, workers need to place the current transformers with the central copper plates one by one under the pressing plate. After each pressing is completed, the current transformer is removed and then the next current transformer is placed. Workers need to perform manual operations frequently, and the pressing efficiency is low. Summary of the Invention

[0005] The purpose of this invention is to provide a press-fit machine for the center copper sheet of a current transformer, which can press-fit the center copper sheet of multiple current transformers at one time. After pressing, the current transformers can be easily removed, reducing the cumbersome operation for workers and improving pressing efficiency.

[0006] This invention is achieved through the following technical solution: a press-fitting machine for the center copper sheet of a current transformer, comprising: A base, wherein a central seat is fixedly disposed in the middle of the base; a rotating disk is rotatably disposed outside the central seat, and a rotating component is disposed on the base for driving the rotating disk to rotate around the axis of the central seat; Multiple arc-shaped mounting bases are distributed around the top outer edge of the rotating disk and can be enclosed to form a ring. Each arc-shaped mounting base has multiple first through slots for placing current transformers. The rotating disk has second through slots that correspond one-to-one with the first through slots. The pressing mechanism is set on the base and located on one side of one of the arc-shaped mounting seats on the rotating disk, and can press the central copper sheet on the arc-shaped mounting seat to the current transformer. The feed chute, located on the base and on one side of another arc-shaped mounting seat on the rotating disk, is used to guide the pressed-fit current transformer out. The ejection mechanism includes a lifting member and a pushing member. The lifting member is disposed on the base and located directly below the arc-shaped mounting seat near the guide chute. The pushing member is disposed on the center seat and faces the guide chute.

[0007] Furthermore, the lifting component includes a lifting cylinder, a lifting seat is provided on the piston rod of the lifting cylinder, a plurality of lifting columns are provided on the lifting seat, the lifting columns are hinged on the lifting seat and can rotate in a direction away from the center of the rotating disk, and a blocking member for restricting the rotation of the lifting columns is provided on the lifting seat. When the lifting seat abuts against the bottom surface of the rotating disk, the blocking member releases the restriction on the rotation of the lifting columns.

[0008] Furthermore, the lifting column includes a solid section at the bottom and a hollow section at the top. A hinge plate is provided at the bottom of the solid section. A hinge seat is provided on the lifting base. A back baffle is provided on the side of the hinge seat near the center of the rotating disk. The blocking member is located on the side of the hinge seat away from the center of the rotating disk.

[0009] Furthermore, the blocking component includes a telescopic baffle, which is slidably connected to the lifting seat. A base plate is provided at the bottom of the telescopic baffle, and a tension spring is connected between the base plate and the lifting seat. Abutment rods are provided on both sides of the base plate. When the lifting seat abuts against the bottom surface of the rotating disk, the abutment rods drive the base plate and the telescopic baffle to move downward relative to the hinge plate, thereby releasing the restriction of the telescopic baffle on the rotation of the hinge plate.

[0010] Furthermore, the pushing component includes a pushing cylinder, and an arc-shaped pushing strip is provided on the piston rod of the pushing cylinder, with an inclined abutment surface opened at the bottom of the arc-shaped pushing strip.

[0011] Furthermore, the pressing mechanism includes a pressing seat disposed on one side of the rotating disk, a pressing cylinder disposed on the pressing seat, a pressing plate disposed on the piston rod of the pressing cylinder, and the pressing plate being located directly above one of the arc-shaped mounting seats.

[0012] Furthermore, the press-fit base is provided with a clamping member for allowing the current transformer to pass through the first through slot and be tightly attached to the rotating disk.

[0013] Furthermore, the clamping member is provided in two sets, one set of clamping members is located on the side of the pressure plate facing the center of the rotating disk, and the other set of clamping members is located on the side of the pressure plate away from the center of the rotating disk; the clamping member includes a clamping strip and connecting rods provided on both sides of the top of the clamping strip, and an arc-shaped buffer surface is provided at one bottom end of the clamping strip.

[0014] Furthermore, the rotating component includes a motor bracket fixed to the base, a rotating motor is mounted on the motor bracket, a drive gear is provided on the output shaft of the rotating motor, and a driven gear is coaxially arranged on the bottom of the rotating disk.

[0015] Furthermore, the arc-shaped mounting bases are all detachably mounted on the rotating disk using bolts.

[0016] The technical solution of the present invention has at least the following advantages and beneficial effects: 1. This invention installs multiple arc-shaped mounting seats on a rotating disk, enabling the pressing mechanism to press multiple current transformers mounted on the arc-shaped mounting seats at once. After each pressing is completed, the rotating disk drives the arc-shaped mounting seats to rotate, moving the next arc-shaped mounting seat to the underside of the pressing mechanism to facilitate the pressing of the next set of current transformers. Simultaneously, the pressed current transformers are moved from the underside of the pressing mechanism to a position close to the guide trough. The lifting component lifts the pressed current transformers upwards, and then the pushing component pushes the pressed current transformers into the guide trough. This eliminates the need for frequent manual operation by the operator, improving pressing efficiency.

[0017] 2. By setting a clamping element on the pressing base, when each current transformer moves to the bottom of the pressing plate, the upper and lower surfaces of the current transformer are respectively in contact with the clamping element and the clamping strip. During the pressing process, the current transformer has high stability and is not easy to shake, which would affect the pressing effect.

[0018] 3. This invention rotatably mounts the lifting column on the lifting base and limits the position of the lifting column by the blocking component. During the process of lifting the current transformer upward, the front and rear sides of the hinge plate are restricted from rotating by the back baffle and the blocking component, respectively, which can ensure the stability of the current transformer during the lifting process. When the lifting base abuts against the bottom surface of the rotating disk, the blocking component releases the restriction on the rotation of the lifting column, and the lifting column can rotate to an inclined state under the action of the pushing component, thereby facilitating the removal of the pressed current transformer from the arc-shaped mounting base.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0022] The following detailed description, in conjunction with specific embodiments, further illustrates that this embodiment provides a transformer center copper sheet pressing machine, referring to... Figure 1 , Figure 2As shown, the device includes a base 1, multiple arc-shaped mounting seats 2, a pressing mechanism 3, a guide chute 4, and a push-out mechanism 5. A central seat 11 is fixedly installed in the middle of the base 1. A rotating disk 12 is rotatably mounted on the outside of the central seat 11. A rotating component 13 is provided on the base 1 to drive the rotating disk 12 to rotate around the axis of the central seat 11. Multiple arc-shaped mounting seats 2 are distributed around the top outer edge of the rotating disk 12 and can be enclosed to form a ring. Each arc-shaped mounting seat 2 has multiple first through slots 21 for placing current transformers. The rotating disk 12 has second through slots 121 corresponding to the first through slots 21. The pressing mechanism 3 is set on the base 1 and located on one side of one of the arc-shaped mounting seats 2 on the rotating disk 12, and can press the central copper sheet on the arc-shaped mounting seat 2 to the current transformer. The guide chute 4 is set on the base 1 and located on one side of another arc-shaped mounting seat 2 on the rotating disk 12, and is used to push out the pressed current transformer. (Refer to...) Figure 5 As shown, the ejection mechanism 5 includes a lifting member 51 and a pushing member 52. The lifting member 51 is disposed on the base 1 and located directly below the arc-shaped mounting seat 2 near the guide trough 4. The pushing member 52 is disposed on the center seat 11 and faces the guide trough 4.

[0023] The central copper sheet is inserted through a pre-drilled through-hole in the center of the current transformer, and then the current transformer is placed into the first through-slot 21. When the arc-shaped mounting base 2 rotates to be directly below the pressing mechanism 3, the pressing mechanism 3 presses the central copper sheet into the current transformer. The bottom end of the central copper sheet penetrates the bottom of the current transformer and enters the second through-slot 121. After pressing, the rotating component 13 drives the rotating disk 12 to rotate around the axis of the central seat 11. The rotating disk 12 drives the arc-shaped mounting base 2 to rotate synchronously. The next arc-shaped mounting base 2 moves to be directly below the pressing mechanism 3, and the pressing mechanism 3 continues to press the central copper sheet on the next arc-shaped mounting base 2 into the current transformer. At the same time, the current transformer that has been pressed is moved from below the pressing mechanism 3 to a position close to the guide trough 4. The lifting component 51 lifts the pressed current transformer upward, and then the pushing component 52 pushes the pressed current transformer into the guide trough 4, through which it is guided to the next process.

[0024] Reference Figure 2As shown, the rotating component 13 includes a motor bracket 131 fixed to the base 1, a rotating motor 132 mounted on the motor bracket 131, a drive gear 133 mounted on the output shaft of the rotating motor 132, and a driven gear 134 coaxially mounted on the bottom of the rotating disk 12. After each pressing operation, the rotating motor 132 is started to drive the drive gear 133 to rotate by a specified angle. Under the meshing action of the drive gear 133, the driven gear 134 drives the rotating disk 12 to rotate, thereby causing all the arc-shaped mounting seats 2 mounted on the rotating disk 12 to rotate synchronously to switch the operation state. It should be noted that there are at least three arc-shaped mounting seats 2, one of which is used to place the current transformer with the central copper sheet as a feeding station, one located below the pressing mechanism 3 as a pressing station, and one facing the guide chute 4 as a unloading station.

[0025] Reference Figure 1 As shown, the arc-shaped mounting bases 2 are all detachably mounted on the rotating disk 12 by bolts 22. The arc-shaped mounting bases 2 with different diameter first through slots 21 can be replaced as needed to make them suitable for transformers of different sizes within a certain range.

[0026] Reference Figure 1 , Figure 3 As shown, the pressing mechanism 3 includes a pressing seat 31 disposed on one side of the rotating disk 12. A pressing cylinder 32 is disposed on the pressing seat 31, and a pressing plate 33 is disposed on the piston rod of the pressing cylinder 32. The pressing plate 33 is located directly above one of the arc-shaped mounting seats 2. When the pressing cylinder 32 is activated, it moves the pressing plate 33 downward, thereby simultaneously pressing multiple central copper sheets located below the pressing plate 33 until the central copper sheets completely penetrate the current transformer, ensuring that the pressing is in place.

[0027] Reference Figure 3 , Figure 4 As shown, the pressing base 31 is provided with two sets of clamping members 34 for passing the current transformer through the first through slot 21 and pressing it tightly against the rotating disk 12. One set of clamping members 34 is located on the side of the pressing plate 33 facing the center of the rotating disk 12, and the other set of clamping members 34 is located on the side of the pressing plate 33 away from the center of the rotating disk 12. This allows the current transformer to be clamped on opposite sides of each current transformer, ensuring that the current transformer does not easily shake during the pressing process, thereby ensuring the reliability of the pressing. The clamping member 34 includes a clamping strip 341 and connecting rods 342 disposed on both sides of the top of the clamping strip 341. An arc-shaped buffer surface 3411 is provided at the bottom end of the clamping strip 341. When the rotating disk 12 drives the current transformer to move, each current transformer can pass through the arc-shaped buffer surface 3411 before reaching the bottom of the pressure plate 33. Then the top surface of the current transformer is in contact with the clamping strip 341. At this time, the bottom surface of the current transformer is also in contact with the rotating disk 12, which has high stability.

[0028] Reference Figure 5 , Figure 6 As shown, the lifting member 51 includes a lifting cylinder 511, a lifting seat 512 is provided on the piston rod of the lifting cylinder 511, a plurality of lifting columns 513 are provided on the lifting seat 512, the lifting columns 513 are hinged on the lifting seat 512 and can rotate in a direction away from the center of the rotating disk 12, and a blocking member 514 for limiting the rotation of the lifting columns 513 is provided on the lifting seat 512; the pushing member 52 includes a pushing cylinder 521, an arc-shaped pushing strip 522 is provided on the piston rod of the pushing cylinder 521, and an inclined abutment surface 5221 is provided at the bottom of the arc-shaped pushing strip 522.

[0029] The lifting cylinder 511 is activated to drive the lifting seat 512 and the lifting column 513 to move upward, pushing the current transformer to move upward and gradually disengage from the first through groove 21. When the lifting seat 512 abuts against the bottom surface of the rotating disk 12, the blocking member 514 releases the restriction on the rotation of the lifting column 513. At this time, the lifting column 513 can rotate. By pushing the cylinder 521 to drive the arc-shaped push bar 522 to move, the current transformer can be moved out of the first through groove 21 and fall into the guide trough 4.

[0030] Reference Figure 6 , Figure 7 As shown, the lifting column 513 includes a solid section 5131 at the bottom and a hollow section 5132 at the top. A hinge piece 5133 is provided at the bottom of the solid section 5131. A hinge seat 515 is provided on the lifting seat 512. A back baffle 5151 is provided on the side of the hinge seat 515 near the center of the rotating disk 12. A blocking member 514 is located on the side of the hinge seat 515 away from the center of the rotating disk 12. When the lifting cylinder drives the lifting seat 512 and the lifting column 513 to rise, the hollow section 5132 at the top of the lifting column 513 can be fitted over the outside of the central copper sheet, and the top of the hollow section 5132 can abut against the bottom surface of the current transformer, thereby lifting the current transformer upward. During the process of lifting the current transformer upward, the front and rear sides of the hinge piece 5133 are restricted by the back baffle 5151 and the blocking member 514 respectively, so they cannot rotate, which can ensure the stability of the current transformer during the lifting process. When the lifting seat 512 abuts against the bottom surface of the rotating disk 12, the blocking member 514 releases the restriction on the rotation of the lifting column 513, and the lifting column 513 can rotate to an inclined state under the action of the pushing member 52, thereby facilitating the removal of the pressed current transformer from the arc-shaped mounting seat 2.

[0031] Reference Figure 7As shown, the blocking member 514 includes a telescopic baffle 5141, which is slidably connected to the lifting seat 512. The bottom of the telescopic baffle 5141 is provided with a base plate 5142, and a tension spring 5143 is connected between the base plate 5142 and the lifting seat 512. Both sides of the base plate 5142 are provided with abutment rods 5144. When the lifting seat 512 abuts against the bottom surface of the rotating disk 12, the abutment rods 5144 drive the base plate 5142 and the telescopic baffle 5141 to move downward relative to the hinge piece 5133, so as to release the restriction of the telescopic baffle 5141 on the rotation of the hinge piece 5133. At this time, when the pushing member 52 applies a pushing force to the current transformer, the lifting column 513 as a whole can rotate so that the current transformer is in an inclined state, thereby facilitating separation from the arc-shaped mounting seat 2 during the continued pushing process.

[0032] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
